 * `name`: The name of the strategy. The default name is `google_oauth2` but it can be changed to any value, for example `google`. The OmniAuth URL will thus change to `/auth/google` and the `provider` key in the auth hash will then return `google`.
 
 * `access_type`: Defaults to `offline`, so a refresh token is sent to be used when the user is not present at the browser. Can be set to `online`. More about [offline access](https://developers.google.com/identity/protocols/OAuth2WebServer#offline)
 
-* `hd`: (Optional) Limit sign-in to a particular Google Apps hosted domain.  More information at: https://developers.google.com/accounts/docs/OpenIDConnect#hd-param
+* `hd`: (Optional) Limit sign-in to a particular Google Apps hosted domain. This can be simply string `'domain.com'` or an array `%w(domain.com domain.co)`. More information at: https://developers.google.com/accounts/docs/OpenIDConnect#hd-param
 
-* `skip_jwt`: Skip JWT processing. This is for users who are seeing JWT decoding errors with the `iat` field.
+* `jwt_leeway`: Number of seconds passed to the JWT library as leeway. Defaults to 60 seconds.
 
+* `skip_jwt`: Skip JWT processing. This is for users who are seeing JWT decoding errors with the `iat` field. Always try adjusting the leeway before disabling JWT processing.

 * `login_hint`: When your app knows which user it is trying to authenticate, it can provide this parameter as a hint to the authentication server. Passing this hint suppresses the account chooser and either pre-fill the email box on the sign-in form, or select the proper session (if the user is using multiple sign-in), which can help you avoid problems that occur if your app logs in the wrong user account. The value can be either an email address or the sub string, which is equivalent to the user's Google+ ID.
 
 * `include_granted_scopes`: If this is provided with the value true, and the authorization request is granted, the authorization will include any previous authorizations granted to this user/application combination for other scopes. See Google's [Incremental Autorization](https://developers.google.com/accounts/docs/OAuth2WebServer#incrementalAuth) for additional details.
 
 * `openid_realm`: Set the OpenID realm value, to allow upgrading from OpenID based authentication to OAuth 2 based authentication. When this is set correctly an `openid_id` value will be set in `[:extra][:id_info]` in the authentication hash with the value of the user's OpenID ID URL.
